Randy mentioned the E-460 heads, and I have had my hands on a couple of them. My understanding of them is that they are more or less like the D-460 head, but come with the peanut size port, and the aformentioned revised Pro Stock bolt pattern for the A-500 short deck block.

Hope this helps,

The E460 heads were ~ a copy of a Olds prostock head of that era. D460 is "like" a C460 in that it is/was a big block Yates cyl. head.

Call 'em whatever you want ... that was not the ORIGINAL part number of an 18 head bolt head.


Randy, I'm like Bret. What point are you trying to make? I've done 57 sets of C-460 heads in my time, including BossHoss's (who started this thread) heads. All of those C-460 heads were 18 bolt heads. They utilize the OEM 10 bolt x 9/16" pattern, plus four more 7/16" across the bottom and four more 7/16" across the top in the valley, for a total of 18 bolts.

As for "ORIGINAL" are you saying it was the bastard pro stock B-460 head? If so, I've seem some of them be 10 bolt heads and some of the later ones be 18 bolt heads.

My understanding of the D-460 head is that they have the same ports as a C-460, but a revised head bolt pattern for the A-500 Pro Stock block,,,,and it is an 18 bolt pattern.

Charlie, I know you probably have all your old catalogs from Ford Motorsport SVO.

Open up one from about 1994, 1995, 1996 about when they were first offered, to I think page 42 to 45; (all those early catalogs had pretty much the same content on the page numbers).
The C460 & D460 head difference is explained there. The "D" did have the Pro Stock 18 head bolt hole locations like the "E" head.
By 1998 the "D" designation was dropped and the "C" got 8 more bolt holes.

Just trying to convey a little history but, people here don't care or seem to want to know about where or how it all started.
little more history . Febuary 1997 I got a pair of C460 18 holes for bolts/studs

Funny thing this interweb. The simplest questions are often the most fun.

No offense taken here Randy. I was 35 years out of kindergarten when those heads came out but was not aware of the earlier version.

I simply did not understand your point until you explained it fully. Like Uncle Charlie I learned something today. And for an old dog like me that is always a good thing.

Got my answer on the tool and found out about something I didnt know. Very Happy

A lot of questions about those "Yates" heads for a big block engine came through the Ford Motorsport hotline back then and a lot of the information was never put into the catalog. Many people were simply referred to "Raceparts Dustribution" in North Carolina until all the facts of the different iterations became known.
Then they changed the product, lol.
